Hi,
Apart from thinking why you want or need multiple controllers in the same line, you need to be sure not to create loops in the line.
As you have all 3 controllers in the same TP line and connected to IP you have created 3 loops, a controller receives a telegram on TP and sends this to IP and the other 2 devices are receiving this on IP and sends it again to the TP bus, and again and again... so this is what you notice.
To avoid this you need to disable KNX IP features in the KNX settings on at least 2 of the 3 controllers, this way the IP telegrams are not received and sended on the KNX TP bus anymore.
Normally you can have only one! KNX interface in a single TP line, so if you have any standard KNX IP interface / router already in the TP line you always need to disable KNX IP features in the controller.
